Live within your means… if not below them. The way you’ve been talking all this time, it sounds like you’re struggling for cash. If you’re saying you could “swing” a $10,000 car loan, it doesn’t sound like you can really afford it. I’d sell this thing, and get an inexpensive car until you’re out of school, defnitely don’t go out and buy a cummins diesel as a DD. Thats just f’n stupid, sorry but it really is.
